The electrical/switch inside the passenger side door caught on fire, with out warning, while driving. There was a passenger in the vehicle at the time. Driver pulled over when smoke was visible. Flames were soon visible, driver poured water on the flames in effort to extinguish the fire. Flames were reduced but the door began to melt and the window shattered. Emergency services arrived at the scene shortly after calling 911. State police, fire, and ambulance arrived shortly after. Thankfully there were no injuries. The insurance was also called and a claim was filed. An adjuster was assigned to the claim to inspect the cause of the fire. After reading numerous reports of the same incident it sounds like this is a known issue that Toyota has not taken responsibility for. Serious injury could have occurred to the driver and passenger if quick action was not taken.
